In image 2 the cup and rings could be interpreted as being mushroom-shaped. Agaricus type - like the Field mushroom or Fly agaric. Just about. In image 3 there's a splayed 'W' character in front of the cup and ring motif. I've seen very similar W motifs on boundary stones on the Bolton moors which I'd always assumed were medieval, and the initial of 'William' (de Ferrers), an early owner of the land.
